Answer:
- domain: [0, 7]
- range: [-2, 4]
- is a function? YES
Step-by-step explanation:
The domain is the horizontal extent, which is from x=0 to x=7.
The range is the vertical extent, which is from y=-2 to y=4.
The curve passes the vertical line test, so the relation IS A FUNCTION.
_____
The vertical line test asks whether any vertical line intersects the curve at more than one point. If so, the relation is NOT a function.
Answer: 9x^2 - 6x + 8
Step-by-step explanation:
(9x^2 - 2x + 7) - (4x - 1) Subtract like terms
The term 9x^2 doesn't have any other term so it will stay alone.
-2x - 4x = - 6x
7 - (-1) = 8
Put them together to get 9x^2 - 6x + 8
